A method includes receiving data inputted via at least one touch point generated on a touch screen via a first touch mode of the touch screen, detecting whether the at least one touch point on the touch screen satisfies a preset condition, and, in response to the at least one touch point satisfying the preset condition, controlling the touch screen to switch from the first touch mode to a second touch mode. The second touch mode allows data input based on pressure generated on the touch screen.

2. The method according to claim 1 , further comprising, before detecting whether the at least one first touch point satisfies the preset condition: detecting a touch operation applied on the touch screen; and determining the at least one first touch point based on the touch operation.
3. The method according to claim 1 , wherein identifying and responding to the touch operation includes: in response to the touch screen operating in the second touch mode, identifying a pressing touch point out of the at least one touch point; and responding to the touch operation with respect to the pressing touch point.
4. The method according to claim 3 , wherein identifying the pressing touch point includes: calculating a pressure value at each of the at least one touch point; comparing the pressure value at the each of the at least one touch point with a preset pressure; and identifying one of the at least one touch point having the pressure value not less than the preset pressure as the pressing touch point.
5. The method according to claim 1 , wherein the preset condition is a first preset condition, the method further comprising, after controlling the touch screen to switch from the first touch mode to the second touch mode: detecting whether the at least one second touch point generated on the touch screen satisfies a second preset condition; and in response to the at least one second touch point satisfying the second preset condition, controlling the touch screen to switch from the second touch mode to the first touch mode.
6. The method according to claim 5 , the first preset condition is same as the second present condition.
7. The method according to claim 1 , wherein detecting whether the at least one first touch point satisfies the preset condition includes: detecting whether a number of the at least one first touch point is greater than or equal to a preset number.
8. The method according to claim 1 , wherein: the first touch mode is a default touch mode of the touch screen.
9. The method according to claim 1 , further comprising: displaying a control on the touch screen for selecting the first touch mode or the second touch mode.
10. An electronic device comprising: a processor; and a touch screen coupled to the processor, the touch screen being operative in a first touch mode and a second touch mode; wherein the processor is configured to: receive data input via at least one first touch point generated on the touch screen in the first touch mode of the touch screen; detect whether the at least one first touch point on the touch screen satisfies a preset condition, the preset condition including a trajectory of the at least one first touch point satisfying a preset trajectory; and in response to detecting that the at least one first touch point satisfies the preset condition, control the touch screen to switch from the first touch mode to the second touch mode to obtain data input based on pressure generated on the touch screen; receive data input via at least one second touch point generated on the touch screen via the second touch mode of the touch screen; and identify and respond to, in the second touch mode, touch operations corresponding to touch points based on pressure received at the touch points, the touch points including both the at least one first touch point and the at least one second touch point, and the touch operations including both a first touch operation corresponding to the at least one first touch point and a second touch operation corresponding to the at least one second touch point.
11. The electronic device according to claim 10 , wherein the processor is further configured to: detect a touch operation applied on the touch screen; and determine the at least one first touch point based on the touch operation.
12. The electronic device according to claim 10 , wherein to identify and respond to the touch operation, the processor is configured to: in response to the touch screen operating in the second touch mode, identify a pressing touch point out of the at least one touch point; and respond to the touch operation with respect to the pressing touch point.
13. The electronic device according to claim 12 , wherein the processor is further configured to: calculate a pressure value at each of the at least one touch point; compare the pressure value at the each of the at least one touch point with a preset pressure; and identify one of the at least one touch point having the pressure value not less than the preset pressure as the pressing touch point.
14. The electronic device according to claim 10 , wherein: the preset condition is a first preset condition, and the processor is further configured to, after controlling the touch screen to switch from the first touch mode to the second touch mode: detect whether the at least one second touch point generated on the touch screen satisfies a second preset condition; and in response to the the at least one second touch point satisfying the second preset condition, control the touch screen to switch from the second touch mode to the first touch mode.
15. A method comprising: detecting at least one first touch point generated by a first touch operation applied on a touch screen in a first touch mode of the touch screen; receiving data inputted via the at least one first touch point generated on the touch screen; detecting whether the at least one first touch point on the touch screen satisfies a preset condition, the preset condition including a number of the at least one first touch point generated by the first touch operation applied on the touch screen being equal to or greater than a preset number; and in response to detecting that the at least one first touch point satisfies the preset condition, controlling the touch screen to switch from the first touch mode to a second touch mode to obtain data input based on pressure generated on the touch screen; receiving data input via at least one second touch point generated on the touch screen via the second touch mode of the touch screen; and identifying and responding to, in the second touch mode, touch operations corresponding to touch points based on a pressure received at the touch points, the touch points including both the at least one first touch point and the at least one second touch point, and the touch operations including both the first touch operation corresponding to the at least one first touch point and a second touch operation corresponding to the at least one second touch point.
